Question

Which one of the following reactions is expected to readily give a hydrocarbon product in good yields?

Options

• \[\ce{RCOOK ->[Electrolytic][Oxidation]}\]

• \[\ce{RCOO^-Ag^+ ->[Br2]}\]

• \[\ce{CH3CH3 ->[Cl2][hv]}\]

• \[\ce{(CH3)3 CCl ->[C2H5OH]}\]

Answer 1

\[\ce{RCOOK ->[Electrolytic][Oxidation]}\]

Explanation:

\[\ce{2RCOOK ->[Electrolytic][Oxidation] \underset{Anode}{2RCOO^-} + \underset{Cathode}{2K^+}}\]

At anode:

\[\ce{2RCOO^- -> 2RCOO^{\bullet} + 2e^-}\]

\[\ce{2RCOO^\bullet -> R - R + 2CO2}\]

At cathode:

\[\ce{2K^+ + 2e^- -> 2K}\]

\[\ce{2K + H2O -> 2KOH + H2 ^}\]
